Most of the other slightly non-standard CAD/eCAD tools I work with (e.g. Diptrace, PTC Creo Elements) use the right mouse button to drag.So when changing between these applications, it’s slightly confusing/annoying that I need the middle mouse button to drag in QCad.Even worse, the middle mouse button on most mice is the scroll wheel which is not really comfortable to hold while dragging.

So I’d propose an option to switch the function of the middle and right mouse button to allow users to choose the preferable option.

When printing from the preview mode a standard Windows popup shows, letting me select the printer, number of copies and a page range. Unfortunately QCAD (or Windows) ignores the page range - it always prints all pages. So right now I always have to copy the parts I want to print, page them into a separate document and print that instead - even though I got all my stuff nicely lined up for printing on multiple pages.

Using a horizontally/vertically ray means always I have to use a preset Reference point which is 0° for the horizontal Ray and 90° for the vertically Ray. The Reference point Option Box is deactivated.

It would be nice to be able to choose by myself between a Start and End Reference point like the vert./horiz. Line options.

In Autocad when making a dimension when left clicking to place the dimension there is the possibility to drag the dimension to either side of the dimension. This is also possible with Qcad dimension, but it losses the snapping and does not extend the dimension line out to the dimension text.

This is very useful when the two lines the needs a dimension are close together, or overlapping with another.

Many constructions refer to a basis of elements, which stay constant in all follow-ups. As an example there is a floorplan and I would like to create different variations of room layout (e.g. A and B). In my example the basis consists of 30 layers an each variation needs 10 further ones. At last there are 50 different layers in my drawing. Designing layout A needs layer 1 to 30 (basis) and 31 to 40 (A) to be shown, but 41 to 50 (B) must be invisible. Now I modify Var.B which makes me to single click the visibility of 31 to 40 (A) to be not shown and 41 to 50 (B) to be shown. You’ve got it?

It would be great help, to save the set of all shown layers by an individual name in a pulldown-menu. Visibility of my variations could be chosen by userdefined “set of layers”, e.g. “Var-A”, “Var-B” and “Var-A_but_different”. In this way I pick just one set-name in my pulldown-list instead of marking and demarking between countless layers.

In my opinion this tool would be a small aspect in QCad but a giant leap for user-pleasentness

When exporting to SVG it would be helpful if there was a selection of layers to export.E.g. when selecting only layer A in the SVG export dialog, only the objects located/displayed on layer A would be exported to SVG.

As an alternative or additional export feature, there could be an option to export each (non-empty) layer to a separate SVG in one step.The layer names could be used as (part of the) default file names during the export.E.g. Layer A of file XYZ would be exported to “XYZ_A.SVG” while layer B would be exported to “XYZ_B.SVG” etc.

I have created a drawing, where the CENTERS of the most outer lines have a distance of 3.06mm in both X and Y.The line weight of these outer lines is 0.6mm, so the whole image is 3.06mm + 2* 0.6mm/2 = 3.12mm wide and long (center to center plus half of the line weight on every side).Additionally in the export there is a frame around the image, making it 3.12 + 2*frame.The export function however calculates 3.06mm when setting the resolution to 1000Pix/cm, so it does not include the line weights and the outer frame.

This can be done as is in QCAD today, but a quick convenience UI bit would be much appreciated.

Suppose you are working off a bitmap image (transcribing old scan, or you got your apartment’s floor plan like this, because, uh, what tenant needs DXF). It has dimensions markers and everything, but fat chance it’ll be to actual CAD scale after importing.

So, to bring it to scale, you measure between two tick marks on the scale, compute ratio based on measurement and what’s written on the dimension line, and do a scale operation (you can also have QCAD compute the ratio by using math expression, whatever).

That works fine.

A purely just for convenience function to do that would be much appreciated: pick two points, enter what the actual distance between them is, poof bam, appropriate scaling operation is applied.

As a twist, there could be some other bitmap skewing options, like “the points I’ve selected are on a horizontal/vertical line/at an angle of X degrees, then the bitmap would also be applied this transform.

I see that most of this was put in there as a kind of a note-to-self originally, however _SC_NPROCESSORS_ONLN is implemented by every realistically possible targets anyway, so for all practical purposes, this is dead weight.

A couple of questions remain, though:

#ifdef Q_OS_WIN32 should probably be Q_OS_WIN, so as to include win64 as well.

Assuming the real purpose for this function is to determine how many parts a particular task is to be split into in the future, if and when QCAD gets the need to split expensive tasks among multiple CPUS, “core” probably shouldn’t be static - CPUs are hot-pluggable today, and while one probably doesn’t do that on a laptop, it’s not unfeasible in, say, a VDI environment.

In the same way as the Pen tool has a drop down menu, would it be possible to have an option to configure the layer list in the same way. I am trying to create a bit more drawing space and it would be good if I could dock the layer list in the top of my window and only take up a single row space!

I think it would be useful to add a note to the Application preferences dialog window, to explain to the user the difference between ‘Application and Drawing’ preferences and how it effects drawings in QCAD.

It would appear that when QCAD imports a DXF, it reorders the layers into alphabetical order (at least when importing R2011). I have not tested this extensively but on other programs, the order is different from alphabetical. Ideally the operator should be given a choice to order the layers as exported (assuming the DXF format remembers that) or alphabetical. This is because a drawing may have a certain stack up of layers (like a printed circuit board) and then alphabetic ordering is not useful nor desired.

Start up QCAD, (with existing or new configuration, doesn’t seem to matter), “Save as” the completely empty drawing, choose “R15 (dxflib)” on Pro (only this one is available on community), save drawing.

Problem not present when a completely empty drawing saved using Teigha in R15 format is opened (ie. it just results in an empty drawing in AutoCAD 2000). Problem is also not present when saving an existing drawing with Pro (trial) with Teigha and opening it in AutoCAD 2000. Problem does present when trying to open a dxflib-saved drawing in AutoCAD 2000.

Empty drawings created with both dxflib 3.3.4.0 in QCAD Pro 3.4.5 trial and Teigha whatever in QCAD Pro trial 3.4.5 are attached. (Community Git 135fd0 is identical to Pro - same dxflib version.)

According to the help, one requires a middle mouse to pan. Since few standard mice have middle buttons, this is a poor choice for this all important function. The default should be the right mouse button when ever the mouse is placed in an open area with nothing else to select. That way right click can still be used to invoke a pop down menu when ever the mouse is placed over an object that might have a need for pop down menu options. Additionally, the Pan mouse key should be alterable and selectable from a Preferences option, since if one does have a three button mouse, we should not prevent a user from employing this hardware if they have it. The same might be said for all mouse buttons to allow the user to configure the mouse operation to that which is most comfortable and efficient for their tasks.

My request is that all selected entities stay selected after isometric projection, this would be useful for example if you need to modify the projection further after placing!Maybe an extra button could be added in the ISO options?

It would be nice to have in “Application preferences” the possibility to predefine a couple Custom Property Names.Right now I use the Custom Property function to add a DIN and the Material info to every Block. This project has a lot of DIN parts and I have to type again and again the names DIN ... Material ... DIN ... Material ... DIN ... Material ... DIN ... Material ... DIN ... Material ... you got my point

See drawing: I can’t seem to be able to manually change to the “To” variants – that is, override the decision of the label/arrow placement engine.

The circle in the attachment is a borderline example of when even just in this form I would more like it on the outside. If the drawing is crowded in that area, it would be even more useful to have it the other way around.

It would be nice to have the possibility to control the automatic Text orientation in Block attributes.Something what would work like the DIM restriction: I can read the text horizontal and/or from the right side of the drawing sheet.

Right now I have the feeling that the Text orientation is dependent on the tool what I even use.Different tools = different outcomes.
